Best MX9 Loadout in MW2: Best Class, Perks & Attachments

Build the best MX9 loadout in call of duty modern warfare ii with the 32-round mag, Bruen 0900 Grip, and FTAC Castle Compensator.

Attachments:

• Magazine: 32 Round Magazine
• Rear Grip: Bruen 0900 Grip
• Muzzle: FTAC Castle Compensator
• Optional: Mini red dot or reflex sight

The 32-round magazine is recommended to match the standard 30-round capacity of other SMGs and ARs, providing a crucial advantage against skilled players. The Bruen 0900 Grip enhances ADS speed, making the weapon quick to aim. The FTAC Castle Compensator balances the recoil control lost from the rear grip, ensuring ease of use. An optional laser can further increase ADS speed but adds weight.

Best MX9 Class Setup in MW2:

• Secondary: .50 GS or Combat Knife
• Tactical: Flash Grenade or Tear Gas
• Lethal: Semtex or Frag Grenade
• Field Upgrade: Dead Silence or Trophy System

The secondary choice depends on your playstyle. The .50 GS allows for quick kills at range or one-tap headshots, compensating for the MX9's weaker range. The Combat Knife maximizes movement speed for aggressive play or quick escapes. Flash Grenades are highly effective, blinding enemies even with Battle Hardened, allowing for easy clears or advances. Tear Gas provides vision distortion for precise aiming. For lethal equipment, Semtex is ideal for quick kills in camper spots, while Frag Grenades offer versatility with cooking and wall bouncing. Dead Silence enables stealthy flanking, and the Trophy System protects objectives by intercepting enemy throwables. You can eventually equip two field upgrades.

Best MX9 Perks in MW2:

• Basic Perk 1: Double Time
• Basic Perk 2: Scavenger or Battle Hardened
• Bonus Perk: Focus
• Ultimate Perk: Ghost or Quick Fix

Double Time is excellent for SMG players needing to traverse the map quickly. Scavenger helps replenish ammo from fallen enemies, which is useful given the close-quarters nature of SMG combat. Battle Hardened or Bomb Squad are strong choices to counter the fast Time-To-Kill (TTK) by mitigating explosive damage. Focus is recommended as a bonus perk to reduce aim punch from incoming fire, allowing for better sight alignment during engagements. Ghost conceals your position from UAVs in the late game, while Quick Fix aids in regenerating health to contend with multiple enemies simultaneously.
